Sammanfattning

We investigate the extraction plan of present-biased decision makers managing a renew-able resource stock whose growth is uncertain and which could undergo a rapid and sig-nificant change when stock falls below a threshold. We show that the Markov-Nash equi-librium extraction policy is unique, time consistent, and increasing in resource stock. An increase in the threshold leads to increased resource extraction, rather than the precau-tionary reduction in extraction often observed with exponential discounting. An increase in the degree of present bias also leads to an increase in resource extraction. Our analy-sis suggests that accounting for and appropriately dealing with resource managers' present bias may be important to understand resource use sustainability.(c) 2023 The Author(s).
